MICROANATOMY

Detailed explanation-1: -The bone marrow makes blood cells and stores fat. Spongy bone (also called cancellous bone) is made up of small, needle-like pieces of bone arranged like a honeycomb. Spongy bone helps to lessen the weight of a bone while still providing strength.

Detailed explanation-2: -Cancellous tissue, also known as cancellous bone, spongy bone or trabecular bone, is characterized by its spongy, porous, honeycomb-like structure and is typically found at the ends of long bones.

Detailed explanation-3: -Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow. The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.

Detailed explanation-4: -The outer layer has a thin coating called the periosteum. Inside bones there is a supporting structure with interconnecting bony plates and rods called trabeculae. This structure is called trabecular or spongy bone because it looks a bit like sponge. Bone marrow is found in the “holes” of the spongy bone.

Detailed explanation-5: -Spongy bone, also known as cancellous bone, is composed of a lattice-like arrangement of osteocytes known as trabeculae.
